A building's seismic isolation and snubber system for a seismic isolation mechanism instantly activated includes sensors, a processing unit, absorber systems, hydraulic oil pressure systems and multilayer sliding systems. In this regard, a sensor detecting any earthquake-induced strike and dip in a building's quadrant of operation could supply an oblique angle to the processing unit in which the oblique angle thereof is transferred to any hydraulic oil pressure system's coefficient of damping for the hydraulic oil pressure system's corresponding damping force generated to control and distribute a building's equilibrium, and any multilayer sliding system is used to yield or eliminate any seismic horizontal vibrations for the said elements developing all functions, substantially reducing and distributing earthquake-induced stresses, and delivering a building with seismic vibrations effectively isolated and prevented.
